Quick and Easy Angle Viewing

The Volk G4 is an easy all-around lens to view the angle. It is easy to insert and quickly obtain a good view. It allows you to efficiently and effectively view the angle without requiring any rotation and is comfortable for the patient.

My Go-To Gonio Lens

The Volk G3 is one of my go-to gonioscopy lenses. The flange is great for stabilizing the lens, especially for challenging patients who squeeze their lids or move their eyes. In addition to gonioscopy, the G3 is phenomenal for retina evaluation. I love the magnified stereo image you can get during slit lamp examination of the retina. It allows me to view the retina from posterior pole to ora seratta. I always use my G3 gonio lens when I need a better look at a retinal lesion. I recommend the G3 to all my students.

Frequently Asked Questions

Non-flanged lenses like allow for compression/indentation to open the angle and assess closure, and do not require coupling fluid. Flanged lenses provide stability during diagnosis and are essential for laser procedures but require a coupling gel.
The number of mirrors determines how much lens rotation is needed to view the entire anterior chamber. For example, a G6 provides a 360° view with minimal rotation, allowing for a faster and more comfortable gonioscopy exam.
A gonio lens with 3 mirrors is a multi-purpose contact lens and provides views of both the anterior chamber angle AND the retina. These lenses have a mirror for viewing the anterior chamber iridocorneal angle (gonioscopy mirror), a mirror for viewing the peripheral retina (peripheral mirror), and a mirror for viewing the equator and vortex veins (equatorial mirror). The lens also has a central lens for viewing the posterior pole
